How can I Control Hydrogen Sulphide in my Barn?
Posted in: Environment by admin on | No Comments
Hydrogen sulphide (H2S) is a life threatening gas produced by the anaerobic breakdown of liquid manure. H2S can be released while performing common tasks that involve manure flow or mixing. Short and long-term effects of exposure can have impacts on the health and well being of the exposed person. 100-ppm exposure is immediately dangerous to life or health. Pit pulling can generate up to 1000 ppm. Research is being done to improve building design and manure management systems to minimize H2S exposure in hog barns. The goal is to develop low cost systems that will prevent or reduce worker exposure to high H2S concentration during pit pulling. The first stage is to develop a pit pulling system to allow plugs to be pled from a remote location and prevents backflow of manure or gases when the plugs are put back in. The second stage is to determine reduction of H2S gas when tap water is sprinkled. The third stage is to design and develop a pit scraper system to remove swine manure from the barn on a daily basis and to evaluate the reduction of H2S. A pit puller system has already been developed that is low cost, easy to install/use, and is safe. This system involves a winch in the hallway to mechanically pull the plugs from outside the room. A laboratory apparatus was designed to simulate H2S peak concentrations observed during pit pulling events in barns. This was put in a tank, which was equipped with a nozzle port to spray water solution while the H2S was injected. At this time, both the remote puller and the sprinkling systems look promising to control the H2S exposure of workers at a low cost.
